Abstract: A water detecting pressure-sensing device includes a metal housing including a cavity. A pressure sensor is disposed on a die and configured to generate a signal in response to a pressure variation. A protection medium at least partially fills the cavity and covers the die. One or more electrodes are disposed on the die and are used to detect a presence of a water droplet on the protection medium.

Abstract: An electronic device, such as a smart watch, incorporating a fluid-based pressure-sensing device is disclosed. The fluid-based pressure-sensing device includes an enclosure, a pressure sensor, a diaphragm and a sensing medium. The enclosure includes an opening and the pressure sensor is disposed inside the enclosure. The diaphragm hermetically seals the opening, and the sensing medium transfers a pressure exerted on the diaphragm to the pressure sensor. The sensing medium can be liquid oil filling a space of the enclosure, and the diaphragm is a polymer material. The pressure-sensing device may sense an environmental pressure, which may be used by the electronic device to modify its operations, change information that is displayed, and so on.

Abstract: An apparatus with embedded water detection and heater includes a substrate including a number of conductive traces and a lid including multiple electrodes. Each electrode is coupled to at least one of the conductive traces through vias. A sensor is placed inside a cavity of the lid and is electrically coupled to one or more conductive traces of the substrate. A gel at least partially fills the lid and covers the sensor. The presence of water on the apparatus is detected by measuring a dielectric permittivity between at least two of the plurality of electrodes, and the electrodes can generate heat to eliminate the water.

Abstract: According to some aspects of the subject technology, an apparatus includes a first electrode, a second electrode and a dielectric membrane disposed between the first electrode and the second electrode. The first electrode and the second electrode include a number of pores within a region of an input port of the apparatus. The first electrode, the second electrode and the dielectric membrane form a capacitor that is configured to enable detection of occlusion of the input port by water.
